摘要
国家金融信息大厦采用框架／密柱筒-核心筒结构体系，在第59～60层设置了转换层。文章采用有限元法对转换层结构在各工况下进行了强度和稳定性分析，确定了危险工况及其对应的关键节点，并对关键节点进行了构造设计和力学分析，依据分析结果提出了设计方案，可供类似工程参考。
The National Financial Information Building with the height of 360 m is a mega frame-core-tube structural system ,in which the 59th and 60th floors are its conversion layer .In this paper ,the structural strength and stability of the conversion layer in the building subjected to various load condi-tions were analyzed by using the finite element method .Based on the results of the finite element anal-ysis（FEA） of the conversion layer structure ,a typical key joint was separated from the conversion layer structure with the corresponding boundary condition under the dangerous load conditions .Then the structural design and mechanics analysis of the key joint were conducted .Then the joint design schemes were proposed and evaluated based on the results of the re-analysis .The study can provide a reference for the similar engineering .
